As having made a reg 41 backup of my 3760 before flashing it to 3490 I used WinHex to find the device ID in the 41.bin file, but I was not succesful.
Maybe the ID is crypted or stored in another reg.
I also have a 3750 (unfortunately with a defective LCD/Touch), with this device I would it risk to patch reg 41.

What do you mean by device ID? If it's HWID so there is no need to change it.
Or you mean UnitID?

Yes, that's the UnitID and there is no good reason to want to change that. That is, unless you are wanting to clone another unit (which is not a 'good' reason). Maybe, i've missed something here but i thought you were wanting to change the Model Number from 3760 to 34xx to display on your nuvi splash screen and in WebUpdater as you posted here:

But one question remains. During booting I still see 3760 and the WebUpdater also recognizes a 3760, is there a method to "correct" this issue?

Is that what you are trying to achieve, when you said that you wanted to "correct" this issue?

Also the part quote in your post above is from the GarminDevice.xml from a 3750. I'm now confused.

I dont know why you want to try to brick you units for nothing.
Which is the gain in having 3490 instead of 3790 at start?
If you have to send it to service it wont help for sure. Useless exercizes IMHO.
